Water-stabilized antimicrobial organosilane products, compositions, and methods for using the same

A method for producing an antimicrobial organosilane composition, comprising:

• a) mixing at least one quaternary ammonium salt with at least one glycol ether and water to produce a solution;
• b) adding at least one inorganic acid to the solution to acidify the solution;
• and
• c) adding the solution to the organosilane, the organosilane being of the formula RnSiX4-n, where n is an integer from 0 to 3, each R is, independently, a non-hydrolyzable organic group, and each X is, independently, a hydrolyzable group;
• wherein at least one glycol ether is diethylene glycol butyl ether;
• and
• wherein the quaternary ammonium salt has the following structure:
• wherein each of R38, R39, R40, and R41 are independently selected from the group consisting of alkyl, aryl, and aralkyl, or the nitrogen may be part of a ring system;
• and wherein X is an atom.

A composition formed by mixing the following components a) and b):

• a) an organosilane of the formula RnSiX4-n, where n is an integer from 0 to 3, each R is, independently, a non-hydrolyzable organic group, and each X is, independently, a hydrolyzable group;
• and
• b) an acid stabilizing solution comprising:
• i) at least one inorganic acid;
• ii) at least one glycol ether comprising diethylene glycol butyl ether, and
• iii) at least one cationic surfactant in water, wherein the cationic surfactant is a quaternary ammonium salt having the following structure:
• wherein each of R38, R39, R40, and R41 are independently selected from the group consisting of alkyl, aryl, and arylalkyl, or the nitrogen may be part of a ring system;
• and
• wherein X is an anion.
